mNew European Study Shows TheraSphere® Prolongs Liver Cancer Survival Rates

MDS Nordion, a leading provider of products and services to the global health science market, today announced that the first large European study using Yttrium-90 (Y-90) glass microspheres has been published on the use of TheraSphere®, an innovative radioembolisation therapy for the localised treatment of patients with advanced hepatocellular carcinoma (HCC) or primary liver cancer.

The publication, which currently canbe viewed online/(*see abstract below) and is expected to appear in the November 2010 edition of Hepatology, concludes that radioembolisation with TheraSphere® is both safe and effective, and states that the overall survival rate is similar to that found in another recently published large study analysing Y-90 glass microspheres for the treatment of HCC.

..n

Conducted at MDS Nordion’s European Centre of Excellence in Essen, Germany, the study involved 108 patients, none of whom were eligible for conventional locoregional therapies. Patients achieved a median overall survival of 16.4 months with minimal damage to the surrounding healthy tissue, even in patients with advanced liver cirrhosis or portal vein thrombosis. No lung or visceral toxicity was observed.

The most frequently observed adverse event was a transient fatigue-syndrome.Philip Hilgard, MD, hepatologist and lead author of the paper says, “The outcomes of this study were not unexpected, but it was extremely important for us to be able to substantiate and verify the treatment here in Europe. We feel confident that the publication of our study will help towards giving more patients access to this advanced therapy.â€

About TheraSphere

,

TheraSphere is a liver cancer therapy that consists of millions of small glass beads (20 to 30 micrometers in diameter) containing radioactive yttrium-90. The product is injected by physicians into the main artery of the patient’s liver through a catheter, which allows the treatment to be delivered directly to the tumour via blood vessels.

TheraSphere treatment can generally be administered on an outpatient basis and does not usually require an overnight hospital stay. MDS Nordion is approved (CE Mark) in Europe to distribute TheraSphere for treatment of hepatic neoplasia. MDS Nordion established a European

TheraSphere Centre of Excellence in Essen, Germany to train and educate oncology professionals on the use of this innovative cancer treatment.In addition, there are multiple treatment centres across Europe, including the BCLC Group Hospital Clinic in Barcelona, Spain; Centre Eugene Marquis in Rennes, France; and Istituto Tumori in Milan, Italy.

f

TheraSphere treatment has some common side effects, including mild to moderate fatigue, pain and nausea for about a week. Physicians describe these symptoms as similar to those of the common flu. Some patients will experience some loss of appetite and temporary changes in several blood tests.

nRadioembolization with Yttrium-90 glass microspheres in hepatocellular carcinoma: European experience on safety and long term survival

nAbstractRadioembolization has been demonstrated to allow locoregional therapy of patients with hepatocellular carcinoma not eligible for transarterial chemoembolization or other local therapies.

The aim of this study was to validate evidence of the safety and efficacy of this treatment in a European sample of patients with advanced HCC.

m

Therefore, 108 consecutive patients with advanced HCC and liver cirrhosis were included. Y-90 microspheres were administered in a lobar fashion over the right or left branch of the hepatic artery.

The response to treatment was evaluated by CT imaging applying RECIST and WHO criteria with recent EASL/NCI amendments.

Time to progression and overall survival were estimated by the Kaplan-Meier method. 159 treatment sessions were performed ranging between 1 to 3 treatments per patient.

The mean radiation dose per treatment was 120 (±18) Gy.

According to EASL criteria, complete responses were determined in 3% of patients, partial responses in 37%, stable disease 53% and primary progression in 6% of patients. Time to progression was 10.0 months whereas the median overall survival was 16.4 months

..

No lung or visceral toxicity was observed. The most frequently observed adverse events was a transient fatigue-syndrome.

Conclusions:

Radioembolization with Yttrium-90 glass microspheres for patients with advanced HCC is a safe and effective treatment which can be utilized even in patients with compromised liver function. Since TTP and survival appear to be comparable to systemic therapy in selected patients with advanced HCC, randomized controlled trials in combination with systemic therapy are warranted.
